There are several kinds of dissipative bags that are typically used in the electronic and semiconductor industries. They are:
1. Pink polybags: clear and see-through. The antistatic agents used are usually amines, quaternary ammonium, or hydrophilic surfactants, which are not wash-resist or scrub-resist, are temporarily antistatic. The surface resistivity of these material are 109～1011Ω/sq, yet no shielding effect.
2. Black conductive PE bags: The bags are made of carbon black filled PE. The surface resistivity can reach 103～105Ω/sq. The pro is faster static dissipative rate, while the cons is the potential contamination.
3. Anti-static shielding bags: A multi-layer structure composes of CVD (chemical vapor deposition) aluminum or nickel. The pros are of some shielding and translucent; the cons are the cost, opaque, temporarily antistatic and the reusability.
4. Shielding bags：A multi-layer structure composes of aluminum foil. The pros are the shielding performance, moisture barrier; the cons are the cost, opaque, temporarily antistatic and the reusability.

Kenner provides:
1. Permanently antistatic bags
2. Antistatic bags
3. Shielding bags

Kenner provides various forms of the permanently ESD bagging material. They are:
1. Film: KennElec EcoFilm;
2. Tubing: KennElec EcoTubing;
3. Bags: KennElec EcoBags

KennElec Ecobags are made by multi-layer blown film process. KennElec Ecobags are composed of 2 layers of permanently ESD compounds, the other layers of various polymers to provide different properties for various designs.

1. Permanently antistatic, immune to moisture and washable
2. Clear to see through
3. Barcode readable
4. Good mechanical properties
5. Free of amines and heavy metals
6. Printable
7. Moisture barrier grades available
8. Gas barrier grades available
9. Clean room grades available

1. KennElec Ecobags are permanently antistatic while polybags and most of the shielding bags are not.
2. KennElec Ecobags are permanently antistatic while polybags and most of the shielding bags will lose their antistatic after water washing.
3. The surface resistivity of KennElec Ecobags is independent of humidity while that of polybags is strongly dependent of humidity.
4. KennElec Ecobags are multi-layer structure to provide good mechanical properties while polybags are not.
5. KennElec Ecobags are durable, washable and recyclable while others are not.
6. KennElec Ecobags are free of amines and no contamination while polybags and most of the shielding bags are not.
